In the accompanying drawings like reference numerals represent like parts.

The improved machine comprises the bed plate 1 supported by suitable legs 2, 2 at the corners thereof. Mounted on the bed plate 1 are the brackets 3 and 4 for the purpose of supporting the bearings for the auxiliary power shaft 5 of the machine. Also mounted on the bed plate is the bracket 6 which supports the feeding mechanism for feeding the box heads and box rings referred to hereafter as the feeding device. Below the bed plate 1 are fastened the brackets 7 and 8 for supporting the main power shaft 9 of the machine, see Figs. 10 and 5.

The main power shaft 9 carries the gear 10 for driving the shaft, the cam 11 for operating the yielding take-up device, the cam 12 that operates the feeding device, the cam 13 that operates the feeding device for the paper wrappers, the main forming wheel 14, the cam 15 that operates the locking pin for the forming head, and the cam 16 that operates the mechanism for dividing the box form. On the end of the shaft 9 is provided a hand wheel 17 by which the shaft 9 may be turned manually. The shaft 9 also passes through the stationary cam 18, which cam is fastened to the bed plate in any suitable manner to hold it fixed against rotation in the position shown in -18. The bracket 19 is preferably employed for this purpose.

The auxiliary power shaft 5 carries at its right hand end shown in Fig. 10 the friction clutch 20 which is keyed to the shaft- 5. hfounted to rotate loosely on this shaft is the driving gear 21 which gear carries thereon the mechanism for operating and driving the clutch 20. This shaft passes through a bearing in the bracket 4 on which bracket is carried the cam 22 for operating the clutch 20. Carried on the bracket 4 and surrounding the shaft 5 is the cam drum 23 which cam drum carries the cams for operating the head carriers 24 and 25, the presser feet 26 and 27, and the ejectors 28 and 29 for stripping the finished box off from the box form. The shaft 5 also carries the frame 30 by which the head carriers, the presser feet, etc., are supported for rotation with the shaft. Forged or shrunk on the shaft 5 is the disk 31 to which is fastened the frame 32 which rotates with the shaft. This frame carries the box forms 33 and 34.

Mounted under the bed plate 1 is the bracket 35 carrying the stud 36 on which is mounted the feeding device for the wrapping paper. Also mounted on the bed plate 1 is the bearing 37 in which is mounted the yoke lever 38 whichoperates to move the locking pin 39. Also mounted on the bed plate 1 is the bearing 40 for the link 41 which connects to the link 42 which in turn is connected to the lever 43 which lever operates the yielding take-up device. The lever 43 is mounted to oscil] ate in thebearing44 provided on the frame 45 fastened to the bed plate.

Keyed to the bracket 4 is the cam 22 which cam is stationary. Adjacent to this cam is the gear wheel 21 on which gear wheel is carried the rocking arm 46, which rocking arm carries on its outer end the anti-friction roller 47. The rocking arm 46 is keyed to a pin 48 which is mounted in a bearing 49 in the gear wheel 21. The opposite end of this pin 48 has the cams 50 thereon, which operate when the pin is rocked by the cam 22 to spread the segments 51 and 52 so as to force them into engagement with the drum 53 of the clutch 20. The shape of this cam 22 is such as to force the anti-friction roller 47 out so as to operate the clutch and hold it in operation for a trifle less than half a revolution. This causes the gear 21 for each complete revolution to carry the shaft 5 around for one-half a revolution at which point the shaft 5 is stopped and held at rest by mechanism which will be hereinafter described.

The segments 51 and 52 of the clutch are drawn together by the tension springs 54 and 55, which springs operate as soon as the anti-friction roller 47 has passed the high portion of the cam 22, thereby causing the two portions of the clutch to separate. at

once. In this way the auxiliary power shaft is intermittently rotated a half revolution and then allowed to rest.

Mounted stationary on the bracket 4 is the cam drum 23. The bracket 4 has a hub 56jwhich fits into a corresponding sleeve 57 onthe cam drum 23. The cam drum is fastened to the hub 56 by passing set screws (not shown) through the sleeve 57 against the hub 56. For this and other purposes the cam drum 23 is perforated at 58 and 59 and similar perforations are provided in the cam drum at 90 degrees thereto. A perforation 60 is also provided in the head of the drum on a line with the shafts 61 and 62. Inside of the cam drum 23 are fastened the plates 63, 64 and 65 suitably spaced apart and having their edges cut to form the cam grooves 66 and 67.

Surrounding the shaft 61 is provided a sleeve 68 and surrounding the shaft 62 is a sleeve 69. Mounted on the sleeve 68 is the head carrier 24 and mounted on the sleeve 69 isthehead carrier 25. The sleeve 68 carries an anti-friction roller 70 thereon which is rotated in engagement with the stationary cam groove 66 by which the .backward in the sleeves 69 and 68.

sleeves 68 and 69 and head carriers 24 and 25 are driven forward and back. Mounted on the shaft 61 is the presser foot 26 held in place thereon by the screw 71. At the end of the shaft 61 is provided the bearing plate 72 between which and the presser foot 26 is interposed the ball bearing 73. The presser foot 27 is mounted in like manner. Mounted in the frame 30 are also the shafts 74 and 75 on the forward end of each of which is carried the extension arms 76 and 77. Each of these arms is perforated to embrace the shafts 61 and 62 respectively along which these extension arms can slide. Interposed between these extension arms and the bearing plates 72 are the compression springs 78 and 79 by which the presser feet 26 and 27 are normally held in an advanced position. The shaft 61 is shouldered at 80 and the shaft 62 at 81. With these shoulders the extension arms 76 and 77 engage for the purpose of moving the shafts 61 and 62 The shafts 74 and 75 are each provided with extension arms 83 and 82, which arms carry anti-friction rollers 85 and 84 which antifriction rollers are rotated by the shaft 5 in engagement with the stationary cam groove 67 by which they are driven forward and back.

The extension arms 83 and 82 are sleeved to slide on the sleeves 68 and 69 and the head carriers 24 and 25 are rooved to slide on the shafts 74 and 75. In this way the several parts are prevented from twisting or turning from their correct position.

The head carrier 24 is slotted at 86 and the head carrier. 25- is slotted. at 87-through which slots the heads of the boxes are adapted to drop from the chute'88.

Mounted on the shaft 5 at the left hand end is the box form supporting frame 32. This frame consists of a sleeve 90 mounted on the shaft 5 carrying a disk head 91 at the right hand end as shown in Fig. 5. This disk is provided with bearings 92 and 93 in which are supported the box form shafts 94 and 95. These shafts 94 and 95 are alike. The shaft 94 carries on the end thereof one half of the box form 33: this half consisting of a flange that is formed integrally on the shaft or is shrunk thereon. Mounted to slide on this shaft is a sleeve 96. This sleeve is slotted with four slots as indicated at 97 and 98 through which slots project pins that are fastened in the shaft 94. These pins 99 engage with thepinion 100 supporting it and cause the shaft and sleeve to revolve rigidly therewith. The slots 97 in the sleeve 96 are to permit the sleeve to slide freely along the shaft for a limited distance without interfering with the pinions or the support thereof. The sleeve 96 carries at its left hand end the collars 101 and 102 suitably threaded and screwed onto the sleeve 96. being locked rigidly thereon. Between them are carried the ball bearing collars 103 and 104 between 35 which a ring of balls are interposed, forming a ball bearing therebetween. Mounted in a suitable bearing on the sleeve 90 is the shaft 105 adapted to slide in said bearing. This shaft at its right hand end carries a yoke 106 which is adapted to engage in the annular groove between the collars 104 and 101. A longitudinal movement is im parted to the shaft 105 by means of a lever 107 for the purpose of moving the sleeve 96 longitudinally and separating the rear part of the box form 108, which is carried on the sleeve 96, from the front part" which is carried on the shaft 94. The ball bearing between the collars 103 and 104 is provided so as to avoid undue frictional engagement between the collar 104 and the yoke 106. Carried on the shaft 94 is the nut 109 between which and the sleeve 96 is provided a compression spring 110. This spring tends to push the sleeve 96 forward for the purpose of keeping the two halvesof the box forming head together. The outerend of the shaft 94 is supported in bearing 111 in which it is free to rotate. A large headed screw 112 is fastened in the left hand end of the shaft to prevent endwise movement of the shaft to the right and between the nut 109 and the bearing 111 is provided a ball thrust bearing 113.

Mounted on the main power shaft 9 is the forming wheel 14 which forming wheel is adapted to rotate in line with the box forming heads 33 and 34 and the pinions 100 carried thereon, This box. forming wheel car gone down, leaving the disk head 91 free to ries thereon a segmental rack 114: this rack is supported on the forming wheel by means of screws 115 extending sidewise through slots in the rack into said forming wheel. The rack 1141 has a radial movement on the forming wheelby means of the slotted engagement with said screws 115 and the rack is held in its outward position by means of screws 115 extending sidewise between said rack and the flange 117 on said wheel. This yielding support of the rack facilitates the engagement of said rack with the pinions 100, 100 which pinions drive the box forms 33 and 3 1 and on the rotation of the forming wheel 1 1 the pinion 100 that is in engagement therewith is rotated thereby.

The shaft 5 and the disk 31 and the sleeve and the box forms, etc., carried thereon are all rotated in unison by means of a clutch 20 which, as has already been explained, causes the shaft 5 and the parts connected therewith to rotate a half revolution in unison with the main driving shaft 9 and then permits it to remain idle while the main driving shaft 9 completes its revolution after which it is then driven another half revolution in unison with the main driv-- ing shaft 9', after which it remains idle while the main driving shaft completes another revolution, and so on indefinitely.

The driving gear 10 on the main power shaft 9 and the gear 21 on the auxiliary power shaft 5 are of the same diameter and have the same number of teeth so that the angular velocity of the shaft 5 while in motion is the same as the angular velocity of the main power shaft 9.

Mounted on the bracket 3 are the pins 118 and 39. The pin 39 is pressed upwardly by the compression of the spring 119 so that the upper end thereof engages with the recess 120 provided in the disk head 91 for that purpose. This pin is drawn down out of engagement with the disk head 91 by means of the cam 15 carried on the main power shaft 9. This cam engages with the anti-friction roller 121 carried on the yoke 38 and on the rotation of the shaft forces this yoke down once for each rotation of the shaft. The upper end of the yoke terminates in a fork 122 that engages with the head. 123 on the bottom of the pin 39 so that on the oscillation of the yoke 38, the pin has rotate in unison with the auxiliary power shaft 5 and the clutch 20.

Adjacent to the pin 39 is provided the pin 118 which acts as friction brake for step-- ping the disk 91 at the end of its rotation. For this purpose the beveled. cares 12 1- are provided on opposite sides 91. each of which in turn forming wheel 1 1.

beveled upper end of the pin 11% it down. The pi i 118 is .d

125 which lever is pivoted at 126 on the frame of the shock absorber which is fastened to the under side of the bed plate 1 which bed plate is suitably cut away to accommodate the lever 125 and its bearing 126. The lever 125 has connected thereto a piston stem 127 on the lower end of which apiston 128 which works in a cylinder 129. Below this piston is provided a compression spring 130 in the cylinder which spring is compressed by the forcing down of the pin 118. The cylinder 129 is filled with oil below the piston 128 and as the piston 128 is forced down it forces the oil out from. the cylinder through the vent 181 into the reservoir 182: the size of the opening through which the oil is forced out is regulated by the neodle valve 133 which is threaded at the outer end so as to make it adjustable. This forcing out of the oil through the needle valve 85 is what retards the downward movement of the pin 118 and throws the extra load on the cam 12 1, causing the disk head 91 to come to rest gradually. After the cam 124; has passed the pin 118 the spring 130 acts to force the piston 128 up sucking the liquid back under the piston from the reservoir and pushing the pin 118 up to its normal. position.

Pivoted on the bracket 3 is the lever 10'? which operates to move the sleeve 96 longi tudinally. This lever engages with the hooked end 13 1 of the shaft that is in the lower position as indicated in Fig. 5. This lever is pivoted at 185 and carries on its lower end the anti-friction roller 136 which engages with the can]v 16 that is car ried on the shaft 9, see Fig. 7 i The cam 16 is a single cam and operates on the lever 10? once for each revolution of the shaft 9., causing the shaft 105 that is in engagement therewith to be drawn to the left as shown in Fig. 5 for the purpose of dividing the box form that is connected thereto for a purpose that will be presently described. The cam 16 moves the lever in one direction against the expansion of I the spring 107", which spring normally holds the lever in the no sition shown in Figs. 5 and 7. The lei or 107 may be modified to engage directly be tween the collars 101 and 1041 on the sleeve 96, in which case the shaft 105 may be dis pensed with.

0 these sections presses the paper against the box as it is delivered from the feed mechanismof the wrapping paper. It will be understood, of course, that this wrapping paper is delivered in one, two or more strips, as may be desired, each of the strips being gummed onone side. Preferably the widest Strip of Wrapping paper is placed immediately in contact with the box and is the strip which connects the bottom to the ring of the box: the second strip of paper is preferably tion and is preferably narrower than the on the bottom. The wide strip is pasted di rectly to the box, the second strip is pasted to the first strip, and the third strip, if any, would bepasted to the second strip, or to the first strip or to both, as might be desired.

The first section 138 consists of a segmental piece of metal cut to' the cross section shown in Fig. 20. It is in a single piece and has the length indicated between the marks 138 and 138* in Fig. 18. The section 138 is cut away to provide for the operation of the knife 143 in connection therewith. As shown in Fig. 20, section 138 is provided with a groove 140 deep enou h to take in the flange on thebox head. To the left of this groove, the surface of the section is cylindrical and to the right of this groove, it is slightly tapered or cone shaped and terminates to the right with a flange 141, which flange, however, may be omitted on this section. The cylindrical surface presses the wrapping paper against the ring of the box and presses the decorating paper against the wrapping paper, both of which strips of paper are fed on together. The groove 140 presses the wrapping paper around both sides of the flange of the box bottom and the cone shaped surface to the right of groove 140 presses the paper over, turning it in toward the bottom of the box, puttin it in better position to be operated on by t e second section.

In Figs. 18, 19 and 23, the knife that cuts the wrapping and decorating paper is shown and the construction and operation of this will now bedescribed.

Mounted on the section 138, is the bearing 142, in which is pivotally mounted the cutting blade 143.. The ledger blade is mounted on the section 138 and the bearing 142 is formed in connection with the ledger blade 144. The knife 143 carries thereon the crank 145 to which is connected a link 146, which link is connected in turn to the link 147. This link 147 ati-ts rear end slides in the guide 148 and at its front end is connected to the lever 149 pivoted at 150 on the forming wheel 14. This lever 149 at its 1 trated in cross section in Fig. 21. s1sts of the main segmental section 155 havlower end carries the anti-friction roller 151 which bears against the cam 18, which cam is perforated and supported by the shaft 9 and which is held from rotation by the bracket 19, which rigidly connects it to the bed plate 1. As the anti-friction roller 151 travels around the earn, the knife is drawn back until the roller passes the high point 152 of the cam, upon which the torsion spring 153 causes the lever 149 to rock and E draws the knife 143 down, cutting off paper 1 of sufficient length to wrap once around the i box with a suitable overlap. The link 147 is a diflerent color and is purely for decoral f knife 143. ring of the box so that it does not overlap i adjustable to regulate the travel of the The second forming section 154 is illus- It coning the flanges 156 and 157 thereon. Car- 158 which segment turns up the paper at the open end ofthe box preparatory to having it tucked in. This segment is attached" to flange 156 by means of the screws 159 on which are provided the compression springs 166 interposed between the forming segment 158 and the flange 156, by which the forming segment is yieldingly held in position. By the screws 159, the forming. segment 158 may be adjusted in or out according to the depth of the box that is to be made by the machine. Adjacent to the flange 156 is provided the forming segment 161 which segment is provided with a groove therein to-receive the flange of the box head adjacent to which the forming section 161 extends upwardly to press in against the bottom of the box,the paper that overlaps the bottom. The side of this forming section is slotted to receive the screws 162, which pass through the flange 157 and into the flange 156. The forming section 161 has a limited lateral and radial movement on the screws 169. Interposed between the forming section 161 and the segmental section 155, are

the compression springs 163- which hold the forming section 161 out radially; and be tween the flange 157 and the forming section 161 are also provided springs-164 which The third forming section 167 is shown in Fig. 22. This section has the flanges 168 and 169 thereon, which flanges are substantially the same as the flanges 156 and 157 in formin section 154. It is also provided with the segmental forming section 170 whiclris mounted in the same way as is the forming section 161, but it does not have the forming segment corresponding to 158 in Fig. 21.

All of the sections 138, 154 and 167 are mounted to move radially in the groove 187 of the forming wheel in which they are car ried. Each one of these sections is slotted transversely and radially as shown at 170 in Fig. 20 and through these slots pass the pins 171 on which pins the radial movement is permitted in each section. Each of the sec tions is pressed outwardly in a radial direction by the springs 172. Each of the sections is stepped as shown in Fig. 22 so that when one of the sections is pressed inwardly, it will carry the following section in with it so as to present a uniform forming surface to the box against which the sections press.

This improved machine is provided with automatic feeding mechanism for feeding the box heads, for feeding the rings and for bringing the; rings and box heads together on the box form and for feeding the paper which is wrapped around the rings and box heads for the purpose of joining them to gether. Each of these feeding mechanisms will now be described inturn. Mounted on the bed plate 1 of the machine is the bracket 6 on which is carried the feeding mechanism for the rings and for the box heads. The rings are carried in a hopper 173 and the box heads are carried in a hopper 174. The bottom of the hopper 173 is curved as shown in Figs. 3 and 12 and at the bottom of this hopper is an escapement 175 having the arms 176 and 177 thereon each of which arms has a pin 17 8 and 179 thereon respectively. The arms 176 and 177 constitute a fork and the arms and the pins 178 and 179 are spaced apart vertically so. that the lower pin will engage one ring and the upper pin will engage the succeeding ring. The ends of the pins 178 and 179 are so positioned that the end of one pin will engage the ring opposite thereto before the other pin lets go of the ring opposite thereto. By means of this escapement, the rings are allowed to dropone at a time.

The bracket 6 has an overhanging arm 180 on which the hopper 173 is supported. This arm is slotted immediately under the open ing in the hopper through which slot 182, the ringsdrop onto the curved support 181 shown in Figs. 12 and 15.

Pivoted at 183 on the bracket 6 is the swinging arm 184 having a cone shaped centering head 185 thereon. This cone shaped head is shown in cross section in Figs. 15 and 16. It comprises the central cone 186, having the stem 187 thereon which projects back to a plate 188 having wings extending on either side thereof; the end of the stem 187 is threaded so that the cone 186 and the late 188 can be tied together by the nut 189. gurrounding the central cone 186 is the ring 190, having a cone shaped end of the same taper as the cone 186. This ring 190 has a flange 191 thereon projecting inwardly' therefrom, whichflange is engaged between the spring 192 and the head of the cone 186. The spring presses against the plate 188 at the rear and the flange 191 at the front. so that the parts are normally held in the position shown in Fig. 16. Mounted on the lever 184 is the lever 193. Through the levers 184 and 193 projects the pin 194: around this pin 194 at the rear is a compression spring 195 held in place thereon by the head 196. The lever 193 is normally held forward by the expansion of this spring 195 and holds the cone 186 forward, compressing the spring 192. The ring 190 has the flange 197 which is engaged by the ring 198 carried on the end of the lever 184 and is held back thereby while the cone 186 is held forward by the lever 193. As the spring 195 which presses the levers together is stronger than the spring 192 which tends to push them apart, the parts when all assembled as shown in Fig. 13, will all normally stand in the position shown in Figs. 13 and 15. The lever 193 engages the stem 187 and tends to push it forward to the position shown in Fig. 15. When a box ring has been dropped into the slot 182, the lever 184 will be swung forward by a mechanism hereinafter described causing the cones 186 and 190 to engage with the box ring, pick it up and center it thereon. The cones continue to advance carrying the ring toward the boxform 33 and as it advances, the central cone 186 contacts with the overhangin arm 180 through the plate 188 by which 1ts further advance is stopped. The lever 184 continues to advance compressing the spring 195 and permitting the spring 192 to press the ring 190 forward carrying the ring toward the position shown. in Fig. 16, until it is stopped by its flange 191, but the lever 184 with the ring 198 on the end thereof still continues to advance on the ring 190 and sweeps the box ring from the ring 190 onto the box form 33, as is shown in Fig. 16.

While the foregoing operation is being carried on, the box head feeds down through the chute 88 into the slot 86 of the head carrier 24 and when the box ring is in position on the box form as shown in Fig. 16 and the box head is in position in the head carrier 24, the clutch 20 operates to give the shaft 5 a half turn carrying around the box head and the box ring into contact with the forming wheel 14. While this half rotation is being accomplished, the cams 66 and 67 operate to move the head carrier and presser foot forward to bring the box head into contact with the ring and center it with regard thereto. The head carrier is then withdrawn while the presser foot remains and the operation of the forming wheel foes pplying the strips of paper to the box he gins.

The feeding of the box heads will now be described.

bracket 6 is the bracket 205 onwhich is supported a pin 206. The lever 202 is perforated to embrace this pin. A compression spring 207 ismounted on said pin. This spring is compressed against the head 208 of the pin-by the operating lever 202 while it is moved in one direction by the cam 12 and when the operating lever 202 is released by the cam 12 the expansion of the spring 207 drives the lever 202 in the reverse direction. The lever 202 engages with and 0perates the feeding plate 201 in both direc tions.

-Between the base plate 199- and the bracket 6 an opening is left just wide enough to permit one head to pass therethrough and the reciprocation of the feeding slide 201 causes the box heads to be fed out through said opening into the curved chute 88 illustrated in 10 through which they are deposited into the box head carriers by gravity. The lever 184 is also driven from the lever 202. The lever 184 is in the form of a bell crank pivoted at 183. A link 209 connects the lever 202 with the arm 210 of the bell crank lever 184 so that the oscillation of the lever 202 will cause the oscillation of the bell crank 184 as well.

The escapement that regulates the dropping of the box rings is driven in the following manner: The escapement 175 is mounted to oscillate on the pin 211. This escapement has thereon the lever 212 on the end of which is carried the anti-friction roller 213. This anti-friction roller is held in contact with the bell crank 184 by means of the torsion spring 214, one end of which is fastened to the overhanging arm 180 and the rear end of which is fastened to the lever 212. As the bell crank 184 is moved in one direction, it oscillates the escapement 175 in that direction, twisting the spring 214 and it is moved in the reverse direction, the spring 214' operating on the escapement 175 to oscillate it in the other direction, movingthe bell crank 184 back.

Mountedon the base plate of the hopper is a stud 215 on which the lever 216 is mounted to'oscillate; this lever is driven at one end by the lever 202, the lever 202 moving it in one direction only, the lever 216 being moved in the reverse direction by the torsion spring 215. At its opposite end, this lever has connected thereto alink 217 which engages with the crank 218 keyed to the pin 219, which is mounted to oscillate in a suitable bearing in the overhanging arm 180. This pin on its opposite end carries the finger 220 which finger temporarily holds the box ring in place after it has been dropped into the curved support. 181, that is, the box ring drops into the curved support- 181 as soon as the box form which has received a ring, starts to revolve around the shaft 5, being carried around by the frame 32, and during this interval the fresh box ring is held in the curved support 181 by the finger 220 which finger is drawn aside as soon as the new box form is in place.

When the paper box has been finished on the box form at the bottom of the frame 32, the box form starts to rise and during this upward motion, the ejectors 28 and 29' work to strip thefinished box from the box form so that when the box form reaches the top of the frame 32, it will be ready to receive a new box ring thereon. The construction and operationof these ejectors we are now about to describe. These ejectors are composed of two blocks 221 and 222 which are fastened together by the screws 223 and 224 pinching the. shaft 5 between these blocks. Mounted on the blocks are the rocking arms 225 and 226, the rocking arm 225 being pivoted on an axis 227 and the'arm 226 being pivoted on an axis 228. Each of the arms 225 and 226 terminates in a pair of curved fingers 229 and 230 which curved fingers surround the box forms 33 and 34, being normally placed a little behind them. Each of these rocking arms 225 and 226 is provided with an arm 231 and 232 extending laterally therefrom. Mounted on each of the extension arms 76 and 77 is a bearing 233 and 234 each of which is adapted to support a pin 235 and 236, each of which pins has an anti-friction roller on the free end thereof. Mounted on the arms 231 and 232 in a suitable bear.- ing therefor are suitable pins 237 and 238 each of which carries at one end a plate 239 having a cam lug 240 thereon. This lug normally is carried in the path of the anti-friction roller, carried on the pins 235 and 236. When the extension arms 76 and 77 move backward, the anti-friction roller on the pin 236 at the bottom, engages with the lug 240 and causes the'arm 231 by which it is supported to rock bodily around its support 227, causing the fingers 239 to engage'with and strip the finished box off of the box form. As soon as the anti-fric tion roller on the pin 236 has moved back far enough to pass by the lug 240, the spring 241 operates to push the ejector arm back to its normal position. Each of the arms 231 and 232 is provided with an ear 242 through which passes a stem 243 which stem is fastened on its other end to the frame 30 and between the car 242 and the frame 30 is placed a compression spring 241.

A torsion spring 244 is provided fastened at one end to the ear 242 and at the other end to the screw 245, the screw passing through the pin 237 and locking the head 246 thereon. This torsion spring normally serves to'hold the pin 237 and its plate 239 and lug 240 in the position shown in Fig. 31, with the lug 240 resting against the plate 247 fastened on the arm 231 as a stop for the lug 240. It is these parts which cause the arm 231 to lift when the anti-friction rollers carried by the exten sion arms 76 and 77 engage with the lug 240 when moved in a reverse direction. The arm 231 lifts high enough. to permit the anti-friction roller to pass under the lug 240 after which the arm drops. back into place. When the anti-friction roller moves in a reverse direction, it engages the lug 240 and rotates the plate 239 on which it is carried around the pin 237 without disturbing the position of the arm 231 and when the anti-friction roller has passed the lug 240 and disengaged itself therefrom the torsion spring operates to restore the parts to the position shown in Fig. 31. y r

The mechanism for coating the wrappingpaper with glue and feeding the wrapplng paper through the machine will now be described;

Mounted on the bed plate 1 of the ma chine as shown in Fig. 1 is the supporting frame 45. This frame consists of two-arms which extend downward having lateral extensions thereon at the bottom. Supported on these lateral extensions is a water tank 248 under which water tank is provided a gas burner 249 in which gas is burned under the tank for the purpose of keeping the tank and the water containedtherein hot enough to keep paste in proper condition.

Supported in the water tank is a paste tank 250, see Fig. 39. Supported on the water tank is a frame 251 having thereon feet 252 at the four corners thereof, which feet centerthe frame on the tank and serve as supports for the frame when it is desired to take the frame away from the tank and place it elsewhere for any purpose whatever. Supported on this frame 251 are the stationary spools 253 and 254 which carry the paper with which -the boxes are to be wrapped. In front of these spools are supported the guide rollers 255 and'256 in front of which are the glue rollers 257 and 258; in front of these in turn are the guide rollers 259 and 260. Mounted at the end of the frame is the swinging arm 261 on which are mounted to rotate guide rollers 262 and 263. The glue rollers 257 and 258 have their lower sides immersed in the glue of the glue tank 250;the paper moves over and under the rollers in the direction indicated by the arrow in Fig. 39 and as the paper moves the glue roller revolves, picking up glue from the tank below and spreads it on the under side of the paper which passes over it. Bearing against the glue rollers are the scrapers 264 which are yieldingly pressed against the glue rollers for the purpose of scraping therefrom the surplus glue. The spools 53 and 54 are so constructed as to place a limited tension on the paper as it,

270 and 271 thereon. The lug 269 is perforated to. receive the supporting pm 272 mounted on the frame 261 on which pin 272, the disk rests. The pin 272 is a tapered pin and the socket in the lug 269 which receives it is also tapered, the parts being adapted to fit each other snugly so as to avoid Wabbling of the disk on its supporting pin. The upper end of the perforation on the lug 269 is threaded to receive the bolt 273 and the lock nut 274; the bolt 273 can be adgusted to limit the distance the pin 272 will enter the hole in the lug 269 by which a snug fit is secured between them and the crowding of parts that would interfere with the ready removal of the disk 265 is pre vented. The lug 270 is also perforated to receive the supporting pin 275. The supporting pin 275 is merely a guide; the weight being borne by thepin 272. The lug 271 is provided on the disk 265 for the purpose of making the casting interchangeable for the purpose of forming a right or a left hand disk. The lug 271 can be perforated to re: .ceive a pin on the opposite side corresponding to the pin 275. By boring the lug 269 from the opposite end fromthat shown in Fig. 3 and by putting the bolt 273 and lock nut 274 in to correspond, the disk 265 can beused in the spool 253 instead of the spool 254 as shown in Fig. 38.

Attached to the disk 265 is the housing 276 loosely fastened thereon by several screws 277. This housing has a flange 278 through which the screws 277 may pass.

It has also a shoulder 279 between which shoulder and the disk 275 is a compression ler 281 and engages with the head or dle %i The sleeve 283 has longitudinail groove 286 therein which is engaged by "the pin 28? which permits longitudinal movement of the sleeve along the housing. The sleeve 283 is provided with three circulsr recesses therein adapted to receive the halls 288, which halls make contact with the reduced end 268 of the pin Q6? on the one side and the tapered portion of "the housing. The sleeve 283 is pressed Eon Ward and the housing is pressed backward, by the spiral spring 289. This senses the balls 2-88 to choke between the redeced end. 268 and the tapered porlion clutching the two parts together. To Will be seen that the housing and the pin 268 are always clutched together in .ilie some glece, and the housing 276 is brought closer to "the disk 265 when the disks 265 266 are farther ape-rt. lle'eween the disks 265 and 266 is carried the roll oi? paper which rosy be either Wide or narrow according to kind of work that is losing done there i i It is the Wide-l1 of this paper "rliet determines the spacing spar": Ofliilfi disks end as it is the object oil this port of the invention "i0 drew she disks F265 and 266 together against the paper with a pressure that will be practically uniform at all "times for all Widths of paper.
